Grieving parents whose children have been killed or injured on the roads are calling for speed limits to be cut to 20mph near schools.

Fourteen children will lead the campaign by pressure group Brake, at Llanharan Primary School, near Talbot Green, as part of the National Road Safety Week launched today.

They represent the numbers killed or injured on Welsh roads every week in 2004.

Rachel Jones, 15, from Aberdare, was left paralysed down one side of her body after she was knocked down by a hit-and-run driver in Aberdare on Valentine's Day last year, leaving her unable to walk, talk or feed herself.

Her mother, Sheri Ozdemir, 46, said: 'I know people sometimes go over the speed limit without realising and see speed cameras as being money-making for the government but the public is missing the point - we need to reduce injuries and deaths on the roads.'
